Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4The utility model provides a technical solution: a clamping and fixing device for automated transportation, comprising a support seat 1, a support rod 5 is rotatably connected to the axis center of the upper surface of the support seat 1, a connecting plate 7 is fixedly connected to the upper surface of the support rod 5, a cylinder 8 is fixedly connected to one side of the lower surface of the connecting plate 7, an output shaft of the cylinder 8 is fixedly connected to an upper mounting plate 10 through a movable rod 9, the axis center of the lower surface of the upper mounting plate 10 is fixedly connected to a bidirectional clamping assembly through a limit electric push rod 11, and telescopic assemblies 15 are symmetrically placed on both sides of the lower surface of the upper mounting plate 10 and on both sides of the upper surface of the bidirectional clamping assembly;

[0024] The bidirectional clamping assembly includes a lower mounting plate 12, a square hole 16 is symmetrically opened in the middle of the lower mounting plate 12, and limiting grooves 20 are symmetrically opened on both sides of the two square holes 16. A fixing plate 21 is fixedly connected at one-fourth of the inner cavity of the two limiting grooves 20, and one side of the fixing plate 21 is fixedly connected to the inner clamping plate 24 through a spring 22. The inner side walls of the two square holes 16 are fixedly connected to the second guide rod 17, and the outer clamping plates 18 are symmetrically slidably connected to the two sides of the middle of the second guide rod 17, and the inner sides of the two outer clamping plates 18 are staggered and fixedly connected to the connecting rod 23, and one end of the connecting rod 23 is fixedly connected to the inner clamping plate 24. When the telescopic assembly 15 is retracted toward the middle, the outer clamping plate 18 will be driven to move closer to the middle in the second guide rod 17 through the connecting piece 19, so that the outer clamping plates 18 on both sides clamp the outer side of the stack from the outside to the inside, and when the outer clamping plates 18 move closer to the middle, they will drive the two groups of connecting rods 23 to push the inner clamping plates 24, so that the inner clamping plates 24 clamp the inner side of the stack from the inside to the outside. The opposing clamping assembly adopted in the present invention has a simple structure and low cost, and is suitable for large-scale promotion.

[0025] like Figure 1-4 As shown, the upper surfaces of the two outer clamps 18 are symmetrically fixedly connected with connecting pieces 19, and the connecting pieces 19 are hinged to the bottom end of the telescopic assembly 15. The lower surface of the upper mounting plate 10 is symmetrically provided with mounting grooves, and the inner side walls of the two mounting grooves are symmetrically fixedly connected with the first guide rods 13. The two sides of the middle of the first guide rod 13 are symmetrically slidably connected with sliders 14, and the sliders 14 are hinged to the upper surface of the telescopic assembly 15. When the limiting electric push rod 11 is retracted or released, it will drive the telescopic assembly to retract or extend, and the two ends of the telescopic assembly 15 will respectively drive the slider 14 to slide in the first guide rod 13 and the outer clamp 18 to slide in the second guide rod 17, thereby completing the clamping and fixing of the stacking, and further ensuring the practicality and safety of the device.

[0026] like Figure 1-4As shown, the four corners of the lower surface of the support seat 1 are rotatably connected to universal wheels 2, the outer surface of the support rod 5 is fixedly connected to a gear B6, and the upper surface of the support seat 1 is fixedly connected to a side position close to the support rod 5, and the output shaft of the motor 3 is transmission-connected to the gear A4, and the gear A4 is meshed with the gear B6 for transmission. The universal wheels 2 facilitate moving the main body of the device, and the output shaft of the motor 3 drives the gear A4 to rotate, and the gear A4 drives the support rod 5 to rotate through the gear B6, thereby adjusting the placement angle of the clamped stack, and further improving the practicability of the device.

[0027] like Figure 1-4 As shown, the edges on both sides of the outer clamping plate 18 and the inner clamping plate 24 slide in the limit groove 20, and the axis of the inner clamping plate 24 slides in the second guide rod 17. The outer clamping plate 18 and the inner clamping plate 24 both slide in the limit groove 20 and the second guide rod 17, ensuring stability during displacement.

[0028] Working principle:

[0029] When in use, first start the motor 3 through the start control end control, the output shaft of the motor 3 drives the gear B6 to rotate through the gear A4, the gear B6 drives the connecting plate 7 to turn through the support rod 5, and makes the connecting plate 7 be located above the stacking stack. At this time, the cylinder 8 drives the upper mounting plate 10 to move downward through the movable rod 9, so that the lower mounting plate 12 is placed on the upper surface of the stacking stack, the limit electric push rod 11 extends and drives the telescopic assembly 15 to close to the middle, and the upper end of the telescopic assembly 15 slides in the first guide rod 13 through the slider 14, and the lower end of the telescopic assembly 15 drives the outer clamping plate 18 to slide in the second guide rod 17 through the connecting piece 19, so that the outer clamping plates 18 on both sides clamp the outer side of the stacking stack from the outside to the inside, and the outer clamping plates 18 move to the middle. When the two groups of connecting rods 23 are brought together, they will drive the two groups of connecting rods 23 to push the inner clamping plate 24, so that the inner clamping plate 24 clamps the inner side of the stack from the inside to the outside, and the clamping and fixing effect of the stack is improved by the two-way clamping method, and the spring 22 can perform a certain degree of shock absorption. When the connecting rod 23 pushes the inner clamping plate 24, the connecting rod 23 extends accordingly. When preventing stacking, the limiting electric push rod 11 expands to both sides to drive the inner clamping plate 24 and the outer clamping plate 18 to separate from the stacking, and due to the rebound inertia of the connecting rod 23, the purpose of fast unloading is achieved. The utility model replaces cumbersome and complicated mechanical parts, and adopts a low-cost, simple and efficient way to transport the stacking, while saving the production cost of the enterprise, reducing the failure rate, and is suitable for large-scale promotion.
